While the world is horrified by the novel Coronavirus, scientists at the European Centre for Nuclear Research (CERN) announced the discovery of a never seen before tetraquark. Any finding in particle physics is a phenomenal one because it could tell us a lot about the origins of the universe and how everything came to be. And this discovery is quite charming and quarky (quirky).

Quarks are the elementary particles so any further division of these particles is not possible. This means everything in the universe is ultimately a combination of Quarks. Any new discovery of Quarks  therefore increase our understanding about the origin of universe

When three Quarks come together, they form familiar particles known as Baryons, for instance, protons and neutrons, found in the nucleus of an atom. A tetraquark, in particle physics, is an exotic meson composed of four quarks.

Murray Gell-Mann, recipient of the 1969 Nobel Prize in Physics for his work on the theory of Elementary particles, chose the name ‘Quark’. Another scientist,  George Zweig from CERN also proposed the Quark theory independently of Gell-Mann.

All the new particles are detected using particle accelerators where particles are accelerated at almost the speed of light and collide to look into their subsets. It is like knocking two rocks together so that they break into smaller constituents.

The most recent tetraquark, named X (6900) was discovered by CERN physicists while working on LHCb (Large Hadron Collider beauty experiment). The already known tetraquarks contain a particular combination of two relatively heavy quarks and two light Quarks. On the other hand X(6900) consists of four heavy Quarks: two Quarks and two anti-Quarks.

This exclusive particle made of unusual combinations is a perfect setting for understanding the fundamental force of nature known as Strong Interaction. The strong force is vital to comprehend as it binds together protons, neutrons and the nucleus that ultimately make up matter. Another perk of X(6900)  is its relatively heavy mass, so these are simpler to look at and are more stable as compared to notoriously fast moving-lighter ones.

The paper written by 800 scientists is yet to be peer-reviewed. The bump observed has a statistical significance of more than five sigma (standard deviations) that is good enough to claim the discovery of a new particle.

In any scenario, this unusual discovery will serve as a piece for completing the puzzle of our universe while serving as evidence of the presence of new particles not yet found.

India’s Transgender (Protection of Rights) Act: Why the activists are opposing it?

On July 13, 2020 the Ministry of Social Justice and Empowerment of India notified the release of draft Rules for the much-disputed Transgender (Protection of Rights) Act 2019, and has given citizens 30 days to submit suggestions and objections.

The Ministry first published the draft Rules on April 18, 2020 and asked for comments by April 30, later extended to May 18. Based on the central government’s consideration of the submitted feedback, the updated Rules were once again opened to critique.

As summarised in this analysis by PRS Legislative Research, the Rules lay out the detailed process regarding issuance of Certificate of Identity, and welfare measures, medical facilities and such for transgender people. It also specifies that the National Institute of Social Defence will act as secretariat for the National Council for Transgender Persons.

Analysis

  1. The Act is infamous for claiming to confer the right to self-perceived gender identity, which is also enshrined in the National Legal Services Authority (NALSA) vs. Union of India judgement, but continuously neglecting this right thereby going against both a Supreme Court judgement and its own statement.
  2. This manifested once again in Rule 4 of the first draft of Rules which required a psychologist’s report— while paradoxically insisting that it requires “no medical examination”— as part of the application process. This requirement was removed from the recent draft of the Rules after backlash.
  3. Also, as stated in the Act, it is the District Magistrate who will determine the final “correctness” of the application, essentially stripping transgender people of any supposed right to self determination. It is worth noting that this places the District Magistrate, an executive figure, in a judicial position, one of ‘judging’ the ‘authenticity’ of a person’s gender identity.
  4. The above mentioned application will only provide a Certificate of Identity that states a person’s gender identity as transgender. To be able to apply for a revised Certificate of Identity to change one’s gender to male/female as per Rule 6, a person must undergo gender reassignment surgery and on top of that provide a certificate stating this from the Medical Superintendent or Chief Medical Officer from the medical institution which facilitates the surgery.
  5. This is problematic for a large multitude of reasons, including but not limited to: many transgender people not feeling the need for medical or surgical intervention, the policing of transgender people’s identity as only being ‘valid’ if they undergo surgery, and the sky-high costs of surgery contrasted with large numbers of transgender people living in unsupportive environments and/or being unable to finance their surgery.
  6. The right to self-identification continues to be blatantly violated in Rule 8, under which a District Magistrate can reject an application, following which the applicant has a right to appeal the rejection only within 60 days of intimation of the same, as stated in Rule 9.
  7. The right to self-determination was also thrown out the window when the first draft Rules imposed a penalty on “false” applications, once again referring to the arbitrary power of the District Magistrate. This has also been removed following strongly negative reactions.

It is important to compare the two versions of the Rules despite the second one being arguably better and cognizant of some of the demands made by the citizens and other stakeholders.

The first version of the Rules quite clearly depicted the narrowly cisnormative perspective through which transgender lives are seen by the people in power. Despite the many changes as a result of relentless protests, the Act is nowhere near to truly respecting and empowering transgender people.

The decision to give the final say to the District Magistrate- which some argue made the process harder than it used to be before the Act- and the refusal to provide affirmative action or reservations to ensure representation in positions of authority that transgender people have historically been denied access to.

It also does little to counter discrimination, as is seen most clearly in the punishment of sexual assault and rape being much less than for the rape of a cisgender woman. It advocates for plenty of measures but does pitifully little to ensure or enable these changes.  

History of the Act

The history of the Act is a turbulent one. The 2016 Transgender (Protection of Rights) Bill, was almost immediately slammed by activists, NGOs, other human rights organisations, and citizens, for multiple reasons.

The most derided was the provision to set up a ‘District Screening Committee’ which included the District Magistrate, a chief medical officer and a psychiatrist among others, for the sole purpose of scrutinising a transgender person’s body and identity. It also criminalised organised begging, an activity specifically common among the Hijra community.

The Lower House of the Parliament, the Lok Sabha, rejected all the proposed changes by the parliamentary standing committee along with the demands of the transgender community, and passed the bill with some amendments in 2018. A short-lived victory came in the form of the lapse of the bill due to the 2019 general elections.

However, as soon as the NDA government was re-elected, the bill was reintroduced in the Parliament with some more changes, particularly the removal of the section on District Screening Committees, but was still unsatisfactory.

The full text of this bill was not released when it was approved by the Union Cabinet on July 10, 2019, but on the morning that it was tabled in the Lok Sabha, garnering another consecutive year of protest since it was first introduced.

This is the bill as it exists today, having been passed by the Lok Sabha on August 5, 2019. When the motion to refer it to a select committee failed in the Rajya Sabha, it was passed on November 26, 2019, and received presidential assent on December 5, 2019. Recent developments include a writ petition in the Supreme Court challenging the validity of the Act.

Despite it becoming the law of the land, transgender citizens and activists such as Esvi Anbu Kothazam and Kanmani Ray continue to criticse it and the insidious transphobic thinking that has always guided it.
